21st july : local Interlaken and nearby place like Lake Thun , Lake brienz

I would love to cover these places by self drive car so that can stop at small town and greenery places. Is it advisable or better I use trains , boats since I will have swiss travel pass.

22nd july : Day trip to schilthorn , gimmewald, murren, trumbalbech falls, lauterbrunen valley. Pls advise correct route to cover all this in day trip . Is Harder Kulm comes in these places?

23rd july: I am open for your suggestion on where to use this day . ( Lucerne and mount titlis not interested as have been there before). since next day we are travelling back home , today we don't want very long hectic day. 6-7 hour day max. I am open for self drive car day. pls suggest.

24th july: leave by 12 noon from INterlaken ost - zurich aiarport by train for back home flight.

my further queries:

1) according to above schedule which swiss travel pass is best . Either 8 days consequetive or 4 days flex? ( in flex pass can I use on any 2 consequetive days also.??)

2) In above plan will I be covering anything on famous trains like Glacier express, Golden pass etc? otherwise can add this on 23rd july

3) is it necessary to book any of above schedule trains in advance specially for 21-22-23 july since I don't know the weather forecast.

4) How to get cheapest and reliable mobile date for internet use for these 6 days?

If you take the Swiss Travel Pass Flex you can choose any days to use it. https://www.myswissalp s.com/swisstravelpassf lex/howtouse To know which pass is the best for your specific itinerary you need to plan out all trips you will make (train, bus, boat, cable car) and compare the prices for regular tickets to the rail pass price (and which routes/mountains are free or discounted). Once you have that information you can read our page here on how to choose the best rail pass. There is a spreadsheet there to help with the math. :)

You would need to purchase ordinary tickets from Zurich Airport to/from Bern

In 2015, I spent a day much as you've got planned for 20 July. Good round trip with different options.

Same for the Schilthorn day. Amazing trip. Don't overlook the tram that runs from Murren. Enjoy lunch at Schilthorn.

Consider evening trip to Harder Kulm and dinner at the top. Could be added to either your Jungfrau or Murren day.

A lovely day can be spent on both the lakes. You might get to ride one of both of the genuine paddle steamers. Many local train and bus options to add and make good round trips. They would pass many of the "small towns" or "greenery places" you speak of.

As usual, Lucas has provided some excellent advice. The resources ARE on this site or links thereto. Planning is half the fun.

I need your guidance about distance from zurich airport arrival hall to train station to catch train for intelaken. Is it walkable distance or have to take taxi. I will have 1 big and 1 small trolley bags.
